Die Erfindung betrifft einen Abgaswärmetauscher zur Kühlung von Abgas einer Brennkraftmaschine in einer Abgasrückführung in zwei Stufen. Es ist bekannt, hierzu zwei Abgaswärmetauscher zu verwenden, die nacheinander vom zu kühlenden Abgas durchströmt werden.The invention relates to an exhaust gas heat exchanger for cooling of exhaust gas from an internal combustion engine in an exhaust gas recirculation system in two steps. It is known to use two exhaust gas heat exchangers for this purpose one after the other, to be cooled Exhaust gas flows through become.

Bei Brennkraftmaschinen, die einen Ladeluftkühler zur Kühlung der den Zylindern der Brennkraftmaschine zuzuführenden Ladeluft enthalten, ist es bekannt, das Kühlsystem mit einem Kühlmittelkreislauf darzustellen, bei dem die Brennkraftmaschine in einem Hochtemperaturzweig und der Ladeluftkühler mit dem Rückkühler in einem Niedertemperaturzweig liegt.In internal combustion engines, the one Intercooler for cooling the charge air to be supplied to the cylinders of the internal combustion engine, it is known the cooling system with a coolant circuit to represent, in which the internal combustion engine in a high temperature branch and the intercooler with the recooler in a low temperature branch.
Ein derartiges Kühlsystem ist beispielsweise in der DE-Zeitschrift Schiff & Hafen/Kommandobrücke, Heft 1/1990, Seiten 49 bis 50 dargestellt. Das von einer Kühlmittelpumpe in Umlauf gesetzte Kühlmittel teilt sich nach dem Verlassen der Brennkraftmaschine in zwei Teilströme auf, wobei die Kühlmittelmenge in beiden Teilströmen mit Blenden eingestellt wird. Im Niedertemperaturzweig ist der Rückkühler mit einer durch thermostatgeregelten Kurzschlussleitung und in Strömungsrichtung nachfolgend der Ladeluftkühler angeordnet. Die Lufttemperatur vor Zylinder wird in Abhängigkeit von der Leistung der Brennkraftmaschine durch eine entsprechende Anpassung des Ladeluftkühlmittelstromes durch den Rückkühler eingestellt. Die nicht durch den Rückkühler strömende Kühlmenge fließt ungekühlt im Hochtemperaturzweig parallel zum Ladeluftkühlmittelzweig, dem Niedertemperaturzweig. Beide Teilströme werden vor dem Eintritt in die Brennkraftmaschine wieder zusammengeführt oder gemischt, wobei sich vor dem Motor eine dem Temperaturniveau und der Kühlmittelmenge der beiden Teilströme entsprechende Motoreintrittstemperatur ergibt. Vorteil dieses sogenannten Mischkreislaufs ist, dass bei Teillast zur Vermeidung von Weißrauch eine Vorwärmung der Ladeluft erfolgen kann und somit eine zu starke Abkühlung des Motors vermieden wird. Bei diesem Kühlkreislauf ist jedoch nicht dargestellt, wie im Falle der Abgasrückführung das Abgas gekühlt werden könnte.Such a cooling system is for example in the DE magazine Ship & Port / Command Bridge, Issue 1/1990, pages 49 to 50. That from a coolant pump circulated coolant divides into two partial flows after leaving the internal combustion engine, being the amount of coolant in both partial flows is set with apertures. The recooler is included in the low temperature branch one by thermostat-controlled short-circuit line and in the direction of flow subsequently the charge air cooler arranged. The air temperature in front of the cylinder becomes dependent on the performance of the internal combustion engine through a corresponding Adjustment of the charge air coolant flow through the recooler set. The amount of cooling not flowing through the recooler flows uncooled in High temperature branch parallel to the charge air coolant branch, the low temperature branch. Both partial flows are brought together again before entering the internal combustion engine or mixed, with the temperature level and the amount of coolant corresponding to the two partial flows Engine inlet temperature results. Advantage of this so-called mixed cycle is that at partial load to prevent white smoke, preheating the Charge air can take place and thus an excessive cooling of the Motor is avoided. However, this cooling circuit is not shown how the exhaust gas is cooled in the case of exhaust gas recirculation could.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zu Grunde, einen Abgaswärmetauscher zur optimalen Kühlung von Abgas in einer Abgasrückführung darzustellen, der kostengünstig und bauraumsparend ausgebildet ist.The specified in protection claim 1 Invention is based on the problem of an exhaust gas heat exchanger for optimal cooling to represent exhaust gas in an exhaust gas recirculation, the inexpensive and is designed to save space.
Dieses Problem wird durch die im Schutzanspruch 1 aufgeführten Merkmale gelöst. Die optimale Kühlung bei bauraumsparender Bauweise des Abgaswärmetauschers wird dadurch erreicht, dass der Abgaswärmetauscher in einen Hochtemperaturabgaswärmetauscher und einen Niedertemperaturabgaswärmetauscher aufgeteilt ist, die mit Kühlmittel unterschiedlichen Temperaturniveaus arbeiten und nacheinander von rückzukühlendem Abgas durchströmt werden. Die Abgaskühlung erfolgt in zwei Stufen, in einem Kühlsystem mit einem Hochtemperaturzweig mit Kühlmittel auf hohem Temperaturniveau und einem Niedertemperaturzweig mit Kühlmittel auf im Vergleich zum Kühlmittel im Hochtemperaturzweig niedrigerem Temperaturniveau. Die Kombination eines zweistufigen Abgaswärmetauschers mit einem Kühlsystem mit Kühlmittel auf unterschiedlichen Temperaturniveaus hat auch den Vorteil, dass die Wärmespannungen auf Grund der im Vergleich zu einem einstufigen Wärmetauscher geringeren Temperaturdifferenzen kleiner sind, was nicht zuletzt auch eine einfache und damit kostengünstige Konstruktion ermöglicht.This problem is caused by the im Protection claim 1 listed Features solved. The optimal cooling with space-saving design of the exhaust gas heat exchanger, that the exhaust gas heat exchanger into a high temperature exhaust gas heat exchanger and a low temperature exhaust gas heat exchanger is divided, which is different with coolant Temperature levels work and consecutively from recooling Exhaust gas flows through become. The exhaust gas cooling takes place in two stages, in a cooling system with a high temperature branch with coolant at a high temperature level and a low temperature branch with coolant on compared to the coolant in the high temperature branch lower temperature level. The combination of a two-stage exhaust gas heat exchanger with a cooling system with coolant at different temperature levels also has the advantage that the thermal stresses due to the compared to a single-stage heat exchanger lower temperature differences are smaller, which is not least also allows a simple and therefore inexpensive construction.
Besonders zweckmäßig ist die Einbindung des Abgaswärmetauschers in einen Kühlkreis, in dem der Hochtemperaturabgaswär metauscher in dem von der Brennkraftmaschine abströmenden Kühlmittel liegt und der Niedertemperaturabgaswärmetauscher in einem Niedertemperaturzweig in Strömungsrichtung nach einem Rückkühler.The integration of the exhaust gas heat exchanger into a cooling circuit, in which the high temperature exhaust gas heat exchanger lies in the coolant flowing out of the internal combustion engine and the low-temperature exhaust gas heat exchanger in a low temperature branch in the flow direction after a recooler.

Durch den Betrieb des Niedertemperaturabgaswärmetauscher im Gegenstrom wird zugleich die Wärmeaustauschfläche minimiert.According to claim 4, the coolant can flow in cocurrent to the exhaust gas in the high-temperature exhaust gas heat exchanger and in countercurrent to the exhaust gas in accordance with claim 5 in the low-temperature exhaust gas heat exchanger. By applying hot coolant in direct current to the hot exhaust gas heat exchanger, the heat voltage further minimized and component temperatures reduced. By operating the low-temperature exhaust gas heat exchanger in counterflow, the heat exchange area is also minimized.

Das Abgas wird an den Stirnseiten zu- und abgeführt. Der Abgaswärmetauscher besteht aus einem Hochtemperaturabgaswärmetauscher und einem Niedertemperaturabgaswärmetauscher, die in Längsrichtung hintereinander angeordnet sind und durch Wärmetauschermodule gebildet werden.The exhaust gas heat exchanger according to the invention is according to claim 6 from heat exchanger modules formed, each with a tubular housing with side inputs and Outlet for the coolant and in the housing longitudinal extending exhaust channels are trained. The exhaust gas is fed in and discharged at the end faces.
